Hey Treiberg,

I just replaced my motor mounts and shock on my 240D, auto.

Looking at your pictures you are going to need a longer lever. That ratchet will not crack the 8MM bolt. Need a three foot breaker bar. Try to use 1/2" tools.

Spry the bolt and head with a penetrant. Clean the allen socket. Insert the allen socket and tap it in with a small ball/peen hammer. You will feel it bottom out. And then have at it.

After those are backed out. Remove the shock (replace that bugger). Then remove the rear engine mount. Support the oil pan with a nice piece of wood and jack up engine. Depending on the deteriorated state of the mounts you may have to raise the engine more, seemingly more. After engine is raised the the 4x6mm Allen bolts are a POC. Then simply slide the old mounts out. Pay attention to the orientation of the metal rubber shields.

Respect those Al threads they are very fine. When installing make sure the frame and Al engine mount arm are perfectly lined up - perfectly. Lie under the car perpendicular to the opening. Look up. Make sure the frame bolt hole and arm are lined up. Thread the bolt by hand. If it is lined up it will thread quite number of turns by hand.

Good luck,
Zill.
